'TROLLEY-POLE.

To ctZZ whom it may concern.-

Be it known that 1, CHARLES F.WENsIN- GER, a citizen of the United States, residing at Fremont, in the county of Sandusky and State of Ohio, have invented a new and use ful Trolley-Pole, of which the following is a specification.

This invention relates to trolleys for electric-railway cars, and has for its object to provide a trolley the wheel of which is pivotally mounted for lateral movement on the trolley-head, whereby the same will readily follow the conductor in traveling around curves or in passing over switches.

A further object of the invention is to provide a pivotal connection between the trolley-head and stand, so that the trolley and harp will always be supported in a horizontal plane regardless of the position of the trolley-pole.

A further object is to provide a supporting arm or bracket having a terminal opening formed therein for the reception of one end of the trolleyrope, the latter being extended through an eye or opening in the harp-supporting stand.

A still further object of the invention is to generally improve this class of devices so as to increase their utility, durability, and efficiency.

WVith these and other objects inview the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, and illustrated in the accompanying drawings, it being understood that various changes in form, proportions, and minor details of construction may be resorted to within the scope of the appended claims.

In the accompanying drawmgs, formlng a part of this specification, Figure 1 is a side elevation, partly is section, of a trolley-pole constructed in accordance with my invention; Fig. 2 is a top plan view of the trolleywheel and its associated parts. Fig. 3 is a transverse sectional view taken on the line 3 3 of Fig. 1. Fig. 4 is a perspective view of one of the supporting-arms detached.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The improved device comprises a harpsupporting bracket 5, preferably circular in shape, as shown, and provided wlth a lateral extension 6, having an eye or opemng 7 Specification of Letters Patent.

formed therein for the reception of a trolleyrope 8.

' Pivotally mounted on the support 5 is a harp 9, in which is mounted for rotation the trolley-Wheel 10, bearing against the overhead conductor 11 in the usual manner. The harp 9 is provided with a laterally-extending arm or bracket 12, having an eye 13 formed therein for the reception of the adjacent end of the trolley-rope 8, said harp being swiveled on the support 5 by means of a bolt 14, the threaded end of which is engaged by a clamping-nut 15. The trolley-support 5 is provided with spaced depending lugs 16, between which are mounted substantially arallel rods or bars 17, constituting the tro leypole. The rods 17. form a pivotal connection between the trolley-stand 18 and the harp-support 5, so that said support will be maintained in a horizontal plane regardless of the position of the trolley-pole, and thus permit free pivotal movement of the trolleynarp.

Pivotally mounted at 19 on the stand 18 are the bifurcated arms 20 of supportingbrackets adapted to receive the adjacent ends of the rods 17. The brackets 20 are provided with terminal clamping members 21 and 22, which engage the exterior walls of the rods 17 and are detachably secured together by bolts or similar fastening devices 23. The arms of the supporting-brackets are provided with angular extensions 24, connected by suitable links or bars 25, so that any movement imparted to one of the rods 17 will be imparted to the opposite rod. 1

Extending laterally from the stand 18 is a rod or bar 26, and mounted for reciprocation on said bar is a yoke 27, operatively connected with the pivot-pin 28 of the adjacent bracket 20 through the medium of oppositely-disposed rods 29, there being a coiled spring 30 interposed between the yoke 27 and the stand 18 for yieldingly supporting the trolley-wheel 10 in engagement with the overhead conductor. It will thus be seen that the trolleywheel, together with the harp 9, is free to move laterally on the support 5, so as to accommodate any irregularities in the overhead conductor, and also to permit the trolley-wheel to follow the conductor in traveling around curves or over switches, thus efiectually preventing the wheel from slipping off the conductor. It will also be observed that by rea son of the pivotal connection between the harp-support 5 and the stand 18 the support 5 will always be supported in a substantially horizontal plane regardless of the position assumed by the rods 17 when elevating or lowering the trolley-pole.

Having thus described the invention, what is claimed is 1. In a trolley, a harp-support, a harp pivotally mounted on the harp-support and having a trolley-wheel journaled therein, a stand, spaced brackets pivotally mounted on the stand, substantially parallel rods carried by the brackets and pivotally connected with the harp support, links connecting the brackets, and a spring carried by the stand and operatively connected with the links.

2. In a trolley, a harp-support provided with a lateral extension having an opening formed therein, a harp pivotally mounted for lateral movement on the support and provided with a trolley-wheel, an arm extending laterally from the harp and having an opening, a trolley-rope threaded through the opening in the extension of the harp-support and engaging the walls of the opening in the arm, spaced lugs depending from the harp-support, a trolley-stand, rods pivotally mounted between the lugs and pivotally connected with the trolley-stand, and a spring operatively connected with the rods for exerting an upward pressure on the trolley-wheel.

3. In a trolley, a harp support, a harp pivotally mounted for lateral movement on the support, a trolley-stand, brackets pivotally mounted on the trolley-stand and pro vided with an angular extension, rods form ing a pivotal connection with the brackets and the harp-support, links connecting the free ends of the brackets, an arm extending from the trolley stand, a yoke slidably mounted on the arm and operatively connected with the arms of the adjacent bracket,

and a spring interposed between the yoke and the trolley-stand.

4. In a trolley, a harp support, a harp swiveled on the support and provided with a trolley-wheel, a stand, brackets pivotally mounted on the stand and provided with terminal clamping members, substantially parallel rods seated in said clamping members and pivotally connected in the bottom of the harp-support, links connecting the brackets, and a spring operatively connected with the links for exerting an upward pressure on the trolley-wheel.

5. In a trolley, a harp-sup port, a harp swiveled on the support and having a trolleywheel journaled therein, a trolley stand brackets pivotally mounted on the stand and each having one end thereof provided with clamping members and its opposite end bent laterally to form an angular extension, rods seated in the clamping members and pivotally connected with the harp-support, a link connecting the extensions of the brackets, an arm extending laterally from the stand, a yoke slidably mounted on the arm, rods connecting the yoke and the extensions of the adjacent bracket, and a spring interposed between the yoke and the stand.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
